Outspoken atheist Bill Maher is taking heat for a comment he made over Twitter regarding Tim Tebow and the Denver Broncos’ Christmas Eve loss to the Buffalo Bills. "Wow, Jesus just f—d #TimTebow bad! And on Xmas Eve! Somewhere in hell Satan is tebowing, saying to Hitler 'Hey, Buffalo’s killing them.' " Tebowing, defined by the quarterback's dropping to one knee to pray in the middle of a football game, has become a full-blown Internet meme. Tebow has so far not responded to the offending tweet ... but his defenders off the field are doing their best to block for him.
